CVE-2019-25611

Status: DeferredHigh (8.6)—

MiniFtp contains a buffer overflow vulnerability in the parseconf_load_setting function that allows local attackers to execute arbitrary code by supplying oversized configuration values. Attackers can craft a miniftpd.conf file with values exceeding 128 bytes to overflow stack buffers and overwrite the return address, enabling code execution with root privileges.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Buffer overflow en función de parsing local (AV:L, PR:N, UI:N) permite ejecución de código arbitrario con privilegios root mediante archivo de configuración manipulado.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
